Famous faces including British girl group Little Mix, boy band Union J, TV presenter Kate Garraway and King of Jungle Joe Swash have joined half a million children and families across the UK who will be spending the day or night in a den in support of Save the Children’s latest fundraising campaign, Den Day. Den Day gives everybody an opportunity to get creative for a good cause; by building a den between 29th May and 6th June and getting sponsored to spend a day or night in it, families can raise money to help Save the Children make life better for children across the world.
